i To all whom itmgpy concern:

. useful Improvements in Boxes, of which the following is especification.

This invention relates to certain new and useful improvements in boxesof that class known as folding boxes, and while in the present instanceI have chosen to show the embodiment of the invention in' what is knownto the trade as a suitbox it is evident that the present improvementsare ap plicable to any and all styles and shapes of oxes Irrespective ofthe use to which they are to be put.

The present invention has for its object primarily to provide a boxwhich. shall pose sess maximum strength with lightness without addingmaterially to the cost of its production.

A further object is to provide a cheap yet strong and durable box thatcan be easily and uickly set up and in which the corners s all bestrengthened or reinforced by a diagonal or triangular fold and a corneroverlap which extends upon the side and end of the I dispense with theusual interlocking tongues and slots which are so liable to become tornand which are difficult to interenage and also provide an inner and anouter olded reinforce at the corner.

Other objects and advantages of the invention will hereinafter appear,and the novel features thereofwill be particularly pointed out in theappended claims.

The invention is capable of embodiment in a variety of forms, allembracing the generic idea, some of which are illustrated in theaccompanying drawings, which, with the numerals of reference markedthereon, form a part of this specification, and in which Figure 1 is aperspective view of one portion of a box, it may be the body portion orits cover, constructed in accordance with my invention. an enlargedscale, of one corner of the box,

Fig. 2 is a perspective detail, on

a similar view showing the corner overla just about to be pressed intoits final pos1- tion. Fig. 4 is a perspective detail of one corner of abox, showing a lock for the corner overlap. Fig. 5 is a view of theblank from which thebody portion. or its cover is to be formed. Fig. 6is a perspective detail similar to Fig. 2, but illustratingthe form ofconstruction seen in Fig. i. Fig. 7 is a perspective detail of a portionof a box, showing another modification of'the generic feature of theinvention. Fig. 8 is a perspective view of the box complete. I

Like numerals of reference indicate like parts throughoutthe severalviews. v

In carrying out my invention I employ a blank as seen. in'Fig. 5, inwhich i is the body portion, scored along the lines 2 to form the endsand sides 3 of the box, the overlaps 4, and the rectangular portions 5,which when folded constitute the triangular or diagonalcorner-reinforcing folds. 'i he blank is further scored along the lines6 7, and each rectangular portion 5 is scored diagonally, as along theline '8. Further score-lines S) are provided at the lines of junctionbetween the overlaps 4 and the sides or ends 3, and these overlaps arealso scored at substantially.-

their mid-length, as seen at 10 in line with the score-lines 7.

in forming the box from the blank above described and illustrated inFig. the blank is folded along the lines 2 7 l0 and along the lines 2 6and then along the lines 8, which brings the blank at the corner intosubstantially the shape shown in Fig. 2, and then by pressure on theoverlap in the direction of the arrow seen in lfig. 3 the corner fold orreinforce 11 is brought against the side of the box and the overlapbrought over upon the. inside of the box and embraces the corner and theadjacent portions of the end and side of the box, as seen best in Fig.l. \Vhcn thus pressed i position, the overlaps lit snugly against tileends and sides of the box, as seen in Fig. l, and the ends and sides areheld in a perpendicular position, the corners bcin reinforced upon bothinside and the outside of the box.

In Fig. 7 l have shown substantially the same construction, except thatthe overlaps are lengthened, as shown at 12, so as to reinforce theentire side and end of the box. it will thus be evident that the lengthof the overlaps can be varied as may be deemed most expedient.

- In Fig. illhave indicated bydotted line 13 fold and the other (portionthereof integral how the top edge of the side or end of the box may beslightly cut away, so that when the overlaps are folded down intoposition the folded edge will come flush with the upper edge of the sideor end of the box. This construction also constitutesa form of lock forthe overlap. g 1

In Figs. 4 and 6 I have shown another form of lock for the overlap. Inthis construction I form one portion of the overlap at its scorelinewith a slot or opening 14, and the top edge of the adjacent end or sideof the box over which it folds is provided with a tongue 15, adapted toen age therein, as seen in Fig. 4, the wall of said tongue farthest fromthe corner fold being undercut, as seen at 16, for an obvious purpose,the notch 17, formed by the making of said tongue, serving to receivethe portion of the overlap beyond the slot so as to bring thefoldthereof substantiallyflush with the upper edge of the side or end ofthe box. This notch, however, may .be-dispensed with and the folded edgeofthe overlap lie in a plane above that of the upper ed e of the end orside of the box.

he box-body and its cover are similar-l constructed, and in Fig. 8 Ihave shown suc 1 a box complete. Therefore where in the followin claimsI emplm, the term box niemher i mean to include either the body portionor the cover. The triangular fold and the overlap may be reversed as totheir relative positionsthat is, the fold may be upon the inside of thebox and the corner overlap upon the outside. This would be a more reversal of the construction above described and comes Within the scope ofmy invention, although I consider the former preferable.

From the above it will be seen that I have constructed a novel form ofbox well suited to the purposes to which it is designed, and while thestructural embodiments of the invention as herein disclosed are what Iat the present time consider the preferable one it is evident that thesame is subject to changes, variations, and modifications without departing from the spirit of the invention or sacri-- being any of itsadvantages. I therefore do not intend to restrict myself to the detailsof construction herein disclosed, but reserve the right to make suchchanges, variations, and

modificationsas come properly within the scope of the protection prayed.

What I claim is 1. A box member provided with an interal corner fold andan integralcorner overlap extended over two adjacent sides of the boxmember, one portion of the said overlap being integral with one portionof said corner with the adjacent si 1 2. A box member formed with anintegral 0 of the box.

triangular fold at the corner upon the exterior of said member, and anintegral corner overlap integral with the one side of the box and withthe adjacent ortion of said triangtiar fold, said. overlap eing foldedovertwo adjacent sides of the box and over the said fold.

triangular fold at the corner and a corner overlap bent over adjacentside portions of 3. A box member formed with an integral said member andover the said triangular fold, one of said side portions having a tongueopposite one of the portions of the fold and the adjacent portion of theoverlap having a slot to receive said tongue.

4. A. box member formed with an integral triangular fold at the cornerand a' corner overlap one portion of which is integral with one portionof said fold bent over adjacent side portions of said member, one ofsaid side portions having a tongue. and the adjacentportion of theoverla having a slot to receive said tongue, one wal of said tonguebeing \m dercut.

5. A box formed from a single piece of ma terial and comprisinga bottomand four walls extending at an angle therefrom and connected at thecorner by triangularfolds,

said box bein formed at each corner with an 4 integral over ap extendingover the triangular fold and bent over the edge oftwo adj a- 'j i v centwalls. I

6. A box formed from a single piece of material and comprising a bottomand four walls extending at an an le therefrom and c0 n.

nected at the corner y triangular folds, sairl= box being formed at eachcorner with an 1nte= gral overlap extending over the triangular told andbent over the edge'of two adjacent walls, and a lock between saidoverlap and we 1.

7. A folding-box blank havingscore-lines Y upon its four sides,rectangular portions at the corners with core-lines at right angles toeach other, and additional diagonal'scorelines, and extensions uponopposite 'sidesof i said blank opposite said rectangular portions at theCorners and beyond the same to form corner overlaps to extend around thecorners of the box, said extensions being scored substantiall as and forthe purpose specified.
